It will be evident from the foregoing description that the inventionprovides a bathtub which is. quite inexpensive in comparison tc/bathtubs ,atxpresent in use, and which is of relatively light weightso as to be easily transported and readily installed. The metal liningis of such thinness that it can be provided at low cost and can beeasily and inexpensively fabricated, and the cementitious backing orreinforcement imparts to the structure the necessary strength, withample 'margin, without addingfgre'atly to the weight.

The reinforcement also provides a monolithic structure in which therewill be no problem of leakage at the joints provided between'thesections of the metal lining. The composite wall as described,especially in view of the reinforc iment' provided by the anchoringmembers on the metal lining, embedded in the concrete, provides a verystrong rigid wall. 'From the standpoint of appearance also, the improvedtub is eminently satisfactory by reason of the fact that the surfacesvisible at thelexterior are all of baked ena fuel; or finished in someother suitable manner, and by reason of thefact that a smooth inner tubsurface can readily be provided, and also the fact that the tub can havea substantial rim and a substantial apron of attractive appearance.

In the foregoing description, the backing is referred to as composed ofconcrete, but the backing may, if desired, be formed of aggregate boundby a binder Which is not an hydraulic cement but, for example, of anasphaltic nature or, for example, of a resinous nature. The drawings donot show the metal'lining as having a layer of baked-on enamel, but itis understood that such a layer is provided in a tub of a certain class,the enamel in the cheaper tubs being of what may be termed syntheticporcelain. In a more expensive tub, a porcelain coating, that is to sayan earthenware coating, can be provided. In some cases, the lining maybe made of: stainless steel, and in such a case, no coating layer isnecessary. The article shown in the drawings is used for bathingpurposes, but it will be apparent that the invention is applicable totublike structures such as sinks, laundry'tubs, basins, and otherarticles.

While the foregoing description goes into the various details of thestructure shown for purposes of illustration, it is to be understoodthat the invention is capable of various other embodiments within theprinciples of the invention and the scope of the claims.

1 Claim. 1

This invention relates to new and. useful improvements in a plasticcementitious material, and has more particular reference to so-calledinterior wall plaster.

It is an object of this invention to produce a wall plaster (interior)which is far superior than present day similar plaster.

The invention contemplates the use of brick dust incorporated within theplaster to obtain certain advantages. Bricks have been proven to be anexcellent material for outside walls. Brick dust embodies many of theadvantageous features of brick material, yet, as far as I know, it hasnever been used for interior wall constructions.

To better understand the invention it must be recognized that Portlandcement, and other cementitious substances are not practical as bases forinterior plaster because of their lack of plasticity, or spreadingqualities under the mechanics tool, as well as the lack of adhesion.However, such materials have been made adaptable for these uses by theaddition of finishing lime (hydrated lime) used in various proportionsas the plaster ingredients are being mixed.

It is general practice to use a plaster base mixture with finishinglime, sand, and similar materials in the construction of interior wallplaster. I have discovered by using brick dust, a far superior plasteris obtained. I have discovered that this plaster material may be used toconstruct plaster board as well. The improved interior plaster andplaster board have especially good fireproof and waterproofqualities-they are sturdy and strong; they have low heat conductivityand act as good heat insulation material. The improved plaster andplaster board does not readily crack, crumble nor break under ordinaryconditions of service. It is particularly well adapted to receive coatsof paint and covering materials.

I am aware of the fact that brick dust has been used in connection withconcrete to construct artificial bricks. I am also aware that brick dusthas been used as a coloring material for plastic materials from whichvarious articles are molded. However, the advantages gained by usingbrick dust in an interior plaster or plaster board has never beendiscovered before.

It is another object of this invention to use the largest percentagepossible of brick dust in a plaster or plaster board, commensurate withthe production of a good interior plaster and plaster board.

I believe that an interior plaster is generally characterized by the useof hydrated lime, and the dominating feature of my invention is the useof brick dust with such plaster.

The improved plaster, in accordance with this invention, may be used forall purposes for which interior plasters are now being used.

Still further the invention proposes an 1111-,

this invention specific formulas will now be given for a plaster andplaster board embodying the essential features thereof.

Example I Formula for an interior wall plaster.

Cement plaster base (interior) lbs 100 (71-%%) Finishing lime (hydratedlime) lbs.. Brick dust lbs 20 (14%%) Sand and marble dust lbs 10 (07%%)Water ga1s 10-15 The brick dust which I have used with good results wasobtained from the nearby New Jersey brick factories. This brick dust Icall Jersey brick dust." The ingredients are mixed together in the usualway used for the making of plaster. It will be found that the plasterhas good spreading and adhesive qualities.

Example II Thefollowing formulae may be used for rock lath or plasterboards.

Finishing lime (hydrated lime) lbs-; (30%) Cement plaster base lbs (50%)Sawdust lbs 25 s (12 /z%) Brick dust lbs 15 ('7 /g Water gals 5-10 Theplaster boards are made by mixing the materials and working them in theusual ways.

While I have described the preferred embodiments of my invention, it isto be understood that I do not limit myself to the precise formulasherein disclosed, and the right is reserved to all changes andmodifications coming within the scope of the invention as defined in theappend ed claim.

Having thus described my invention, what I claim as new and desire tosecure by United States Letters Patent is:

An interior wall plaster, consisting of a mixture of a Portland cementbase, 100 lbs.; hydrated lime, 10 lbs. brick dust, 20 lbs. sand andmarble dust, 10 lbs.; and water, 10 to 15 gals.
